I detached two tendons and tore another in my right shoulder. After surgery I needed extra protection when on my mountain bike. This shoulder brace works great but is a bit restricting when breathing hard.I have a grade 3 AC separation. I bought some of the standard shoulder braces first. Use my experience as a guide and save yourself time and money. Get this one. It is side specific and it fits well. The best part? It really does a fantastic job of support AND protection while riding. It has a bit of a shoulder cup that nests on your shoulder and positions it well and provides protection from impacts. I highly recommend this device.Made with quality, but IS NOT as reversible as noted. It does not work very well on the right shoulder, although it is clearly noted it can be used on both. It has a seam and sewn in directional pattern that does not allow it to sit correctly for the right shoulder. It seems that this makes sense since it is a good quality product over all.This is a comfortable and quality fit for the left as described.This brace helped with the repair of the shoulder Supraspinatus while sleeping. Although, the brace was a little odd with the hump on my shoulder during sleeping, it did keet me from feeling pain when sleeping on my side.This brace will last about 6-8 months of regular use before the velcro wears out. It really helped me after I had a massive dislocation and needed shoulder support and compression while riding downhill. I't protected me in one crash, but mostly i wear it to keep the humeral head firmly in the socket . After 11 dislocations, my shoulder is really unstable. I'd recommend getting this for sure. Worked exactly as expectedGreat pressure in the brace, it works fine.This brace was a really good fit. If anyone is looking to keep the shoulder in place, I would definitely recommend this brace.Comfortable. Do his workDurch eine ältere Verletzung habe ich eine Schulter die in der Bewegung und Muskulatur etwas eingeschränkt ist. Zum Schutz beim Aufprall wollte ich die Schulter separat schützen ohne eine Protektoren-Jacke anzuziehen, wo der Schulterschutz nur einer von vielen ist. Und hier macht der Schulter Protektor genau was er soll. Sitzt gut, lässt sich nach ein wenig Übung kinderleicht anlegen, hält seine Position und der Tragekomfort ist auch noch okay.Wenn es sehr heiß ist, sind Protektoren ja generell eher ein Glutherd! ;-)Bei der letzten Ausfahrt musste ich leider auch die Sturzfestigkeit testen und bin seitdem vollends überzeugt. Trotz der Einschlagsseite keine Blessuren an der Schulter davon getragen.Lässt sich auch Problemlos mit einer Protektorweste kombinieren.Verarbeitung und Qualität ist ebenfalls Top.Wer etwas zum separaten Schutz einer bestimmten Schulter sucht kann ich das nur empfehlen.
